Relational Blockchain Database

A non-transitory machine-readable storage medium that provides instructions that, when executed by a processor, cause said processor to perform operations comprising:

• creating a user relational blockchain database that includes a set of one or more system-defined user blockchains and a plurality of user-defined blockchains, wherein the set of one or more system-defined user blockchains includes metadata for managing the plurality of user-defined blockchains, wherein each of the plurality of user-defined blockchains includes a set of one or more fields as defined by a user, wherein the metadata for managing the plurality of user-defined blockchains includes a definition for a field type of at least one field in the set of one or more fields, and wherein at least one of the set of one or more fields relates among the plurality of user-defined blockchains;
• receiving a first command to write data to the user relational blockchain database, wherein the first command includes an identification of a first one of the plurality of user-defined blockchains, an identification of at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains, and a value to write for the at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• generating a first new block for the identified first one of the plurality of user-defined blockchains, the first new block including the value set for the identified at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• transmitting the first new block to a distributed network of blockchain database servers for consensus to add the first new block to the identified first one of the plurality of user-defined blockchains;
• persisting the first new block to the identified first one of the plurality of user-defined blockchains;
• receiving a second command to read data from the user relational blockchain database, wherein the second command includes an identification of the first one of the plurality of user-defined blockchains and an identification of at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• accessing a value of the identified at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• and
• returning the accessed value.

An apparatus, comprising:

• a processor;
• and
• a non-transitory machine-readable storage medium coupled with the processor that stores instructions that, when executed by the processor, cause said processor to perform the following operations:
• create a user relational blockchain database that includes a set of one or more system-defined user blockchains and a plurality of user-defined blockchains, wherein the set of one or more system-defined user blockchains is to include metadata for managing the plurality of user-defined blockchains, wherein each of the plurality of user-defined blockchains is to include a set of one or more fields as defined by a user, wherein the metadata for managing the plurality of user-defined blockchains includes a definition for a field type of at least one field in the set of one or more fields, and wherein at least one of the set of one or more fields is relatable among the plurality of user-defined blockchains;
• receive a first command to write data to the user relational blockchain database, wherein the first command is to include an identification of a first one of the plurality of user-defined blockchains, an identification of at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains, and a value to write for the at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• generate a first new block for the identified first one of the plurality of user-defined blockchains, the first new block to include the value set for the identified at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• transmit the first new block to a distributed network of blockchain database servers for consensus to add the first new block to the identified first one of the plurality of user-defined blockchains;
• persist the first new block to the identified first one of the plurality of user-defined blockchains;
• receive a second command to read data from the user relational blockchain database, wherein the second command is to include an identification of the first one of the plurality of user-defined blockchains and an identification of at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• access a value of the identified at least one of the set of one or more fields of the first one of the plurality of user-defined blockchains;
• and
• return the accessed value.
